摘　　要：目的探讨应用Pentacam三维眼前段分析诊断系统与全景超声生物显微镜(UBM)观察年龄相关性白内障患者手术前后前房直径及前房深度(ACD)的变化。比较两种方法测量结果的差异。方法前瞻性非随机对照临床研究。临床选取行晶状体超声乳化吸出联合人工晶状体(IOL)植入术后的年龄相关性白内障60例(79眼)。应用Pentacam测量术前、术后1周、1个月、2个月的水平前房直径和ACD;应用UBM测量术前、术后2个月的水平前房直径、垂直前房直径和ACD。结果 (1)Pentacam测量结果,术后水平前房直径增加(F=7.170,P=0.009),ACD加深(F=26.439,P<0.05),术后1周、1个月、2个月前房直径、ACD进行两两比较,差别无统计学意义(P>0.05)。(2)UBM测量结果,大部分患眼垂直前房直径大于水平前房直径。(3)Pentacam测量术前、术后2个月的水平前房直径与UBM测量值相比,差别无统计学意义(t=0.231,P=0.818,t=1.017,P=0.311)。Pentacam与UBM测量术前ACD,差别无统计学意义(t=0.153,P=0.995);而测量术后ACD,差别有统计学意义(P<0.05)。结论 (1)Pentacam测量结果显示,年龄相关性白内障患者术后水平前房直径增加,ACD加深,术后1个月前房直径、ACD保持不变。(2)UBM测量结果显示,大部分患者垂直前房直径大于水平前房直径。(3)UBM与Pentacam都可以用于前房直径和ACD的测量,而且对于术前、术后前房直径以及术前ACD的测量结果相似。但测量白内障患者有晶状体眼的ACD时,两种仪器的测量结果不同。两种仪器测量角膜部位不同从而产生差别。但是每一种仪器都有各自的优缺点,使用时应根据不同的目的选用不同的仪器。Objective To study the change in anterior chamber diameter, anterior chamber depth （ACD） after phacoemlsification and foldable intraocular lens （IOL） implantation with Pentacam （Oculus） and panoramic ultrasound biomicroscopy （Meda） To compare anterior chamber diameter and ACD measurements using Pentacam and UBM. Methods It was a prospective non-random controlled clinical study. Seventy-nine of 60 patients with age-related cataract which were performed small incision phacoemulsification and foldable intraocular lens implantation were involved in this study. The anterior chamber diameter in horizontal meridian and ACD were measured by Pentacam before surgery, and 1 week, 1 months, 2 months after surgery. The anterior chamber diameter in horizontal and vertical meridian and ACD were measured by panoramic UBM before and 2 months after surgery. Results （ 1 ） In all patients, the horizontal anterior chamber diameter was widened significantly after surgery （ F = 7. 170, P = 0.009 ）, and the ACD was deepened （F = 26. 439 ,P 〈0.05 ）. There were no statistically significant differenee among the horizontal anterior chamber diameters and the ACD 1 week, 1 months, 2 months after surgery （ P 〈 0.05 ）. （2）The general trend for largest diameter was in the verti-cal meridian measured by UBM. （ 3 ） There were no statistically significant difference between Pentacam and UBM in the horizontal anterior chamber diameters before and 2 months surgery （t = 0. 231 ,P =0. 818;t = 1. 017,P =0. 311）. In the ACD before surgery, the difference between the two devices was not statistically significant （ t = 0. 153 ,P = 0.995 ）, but after surgery the difference was statistically significant （ P 〈 0.05 ）. Conclusion （ 1 ） After phacoemulsification and foldable IOL implantation, Pentacam revealed that the anterior chamber diameter was widened and the ACD was deepened. After 1 week, the anterior chamber diameter and ACD remained unchanged. （2） The largest diameter was in the vertical
